No absolutely not. But the rumor is about Darwin not Edison and has been debunked.
A woman named “Lady Hope” spoke to a church group shortly after the death of Charles Darwin. She claimed that she was at Darwin’s bedside on the day of his death. She also claimed that Darwin recanted on evolution and accepted Jesus on his deathbed. Her claims are not only unsupported, but are directly opposed by Darwin’s daughter, Henrietta. Henrietta stated “I was present at his deathbed, Lady Hope was not present during his last illness, or any illness. I believe he never even saw her, but in any case she had no influence over him in any department of thought or belief. My father never recanted any of his scientific views, either then or earlier. I am upset that the U.S. Christians have fabricated this conversion nonsense. The whole story has no foundation whatever.” February 23, 1922.
